When you notice over time that your clothes dryer has stopped drying, or lost drying ability, it is probably due to a clogged dryer vent. Although many of us tend to neglect the constant maintenance of the dryer vent, it is highly recommended to clean at least once a year. Over the years build up ling will cause blockage in your dryer vent. Therefore, not allow the hot air exhaust outside. If the hot air is limited with venting outside, then, extra pressure will be added on your dryer to let it out. So, you may notice less ability for the dryer to dry, or you may even experience a power surplus. That will cause a fuse to burn out, and then, shutting the ability of the dryer to generate heat.
